ALSA: compress: Fix kernel-doc warnings

2016-11-15T06:28:15Z

Some fields in struct snd_compr have no corresponding comments, and the kernel-doc complains like: ./include/sound/compress_driver.h:162: warning: No description found for parameter 'id[64]' ./include/sound/compress_driver.h:162: warning: No description found for parameter 'proc_root' ./include/sound/compress_driver.h:162: warning: No description found for parameter 'proc_info_entry' Actually all these are internal elements, just put "private:" comment so that they will be ignored.

ALSA: compress: Add function to indicate the stream has gone bad

2016-06-13T15:45:37Z

Currently, the avail IOCTL doesn't pass any error status, which means typically on error it simply shows no data available. This can lead to situations where user-space is waiting indefinitely for data that will never come as the DSP has suffered an unrecoverable error. Add snd_compr_stop_error which end drivers can call to indicate the stream has suffered an unrecoverable error and stop it. The avail and poll IOCTLs are then updated to report if the stream is in an error state to user-space. Allowing the error to propagate out. Processing of the actual snd_compr_stop needs to be deferred to a worker thread as the end driver may detect the errors during an existing operation callback.

ALSA: compress: Pass id string to snd_compress_new

2015-11-30T10:44:59Z

Make snd_compress_new take an id string (like snd_pcm_new). This string can be included in the procfs info. This patch also updates soc_new_compress() to create an ID based on the stream and dai name, as done for PCM streams.

ALSA: compress: Add procfs info file for compressed nodes

2015-11-30T10:44:38Z

This patch implements a procfs info file for compr nodes when SND_VERBOSE_PROCFS is enabled. This is equivalent to what the PCM core already does for pcm nodes. Signed-off-by: Richard Fitzgerald Acked-by: Vinod Koul Signed-off-by: Takashi Iwai

ALSA: Fix spelling typo in Documentation/DocBook/alsa-driver-api.xml

2015-03-04T11:12:59Z

This patch fix spelling typo found in alsa-driver-api.xml. It is because this file is generated from comments in source files, I have to fix source files. Signed-off-by: Masanari Iida Signed-off-by: Takashi Iwai

ALSA: compress: Embed struct device

2015-02-02T13:42:45Z

Like previous patches, this one embeds the struct device into struct snd_compr. As the dev field wasn't used beforehand, it's reused as the new device struct. Reviewed-by: Jaroslav Kysela Signed-off-by: Takashi Iwai

ALSA: compress_driver.h: include sound/core.h explicitly

2015-01-13T15:50:31Z

Fixes the following compilation error: include/sound/compress_driver.h: In function ‘snd_compr_drain_notify’: include/sound/compress_driver.h:177:2: error: implicit declaration of function ‘snd_BUG_ON’ [-Werror=implicit-function-declaration] if (snd_BUG_ON(!stream)) snd_BUG_ON() is defined in sound/core.h but the file is not included explicitly, so include it.

ALSA: compress: fix drain calls blocking other compress functions (v6)

2013-11-07T09:12:27Z

The drain and drain_notify callback were blocked by low level driver until the draining was complete. Due to this being invoked with big fat mutex held, others ops like reading timestamp, calling pause, drop were blocked. So to fix this we add a new snd_compr_drain_notify() API. This would be required to be invoked by low level driver when drain or partial drain has been completed by the DSP. Thus we make the drain and partial_drain callback as non blocking and driver returns immediately after notifying DSP. The waiting is done while releasing the lock so that other ops can go ahead.
